and look over the brands and/or sizes that you are looking for. Then sort by price, and read the reviews/comments for each tire. It goes a long way to helping you formulate a good decision.
I have heard that the Sumitomo tires are great for the price. (I can get 315/35/17s for about $150 a tire. Much less than the $350+ Pilot Sports - even though they are a great tire as I have them on it now.) ---- Check out the deals and hopefully you will have some good luck. I don't run 225s so I don't have any personal experience but I think that tirerack.com can point in the right direction.
